Slots cannot influence Conversation?

Rasa Open Source

I followed this guide (Managing the Conversation Flow ) and did an exercise to change the flow of the conversation by changing the slot value.

However, the slot value has changed, and the dialog flow has not changed.

You’re using a text slot where you need to use categorical. The docs on the text slot point out that:

the assistant’s behavior will change depending on whether the slot is set or not. Different texts do not influence the conversation any further.
